Seat track questions!

Is there a drivers/passenger difference and does the rail with the lever goe toward the center or the doors of the car? I could scarcely even find pictures of any seat bottoms with rails attached.

I am also using 66 seats in my 65 Dart wagon. I “think” the seats are the same or at least really close. I could take a pic of the passenger side bottom with the tracks if that would help. The tracks with the adjuster are side specific and the adjuster knob always goes to the outside towards the door.
